.I also providea pusher plate indicated as H which is provided with thehandle Laterally extending from saidhandle are the arms H to which aresecured the guide pins H which penetrate apertures H in the lugs Hextending downwardly from the members G and G respectively. Itwill beobserved that this pusher plate is fully operative at all positions ofthe member G.

It will be realized that whereas I have described and shown apracticaland operative device, nevertheless many changes might be made in thesize, shape, number and'dlsposition of parts without departing from thespirit of my invention. I therefore wish my description'and drawings tobe taken as in a broad sense il'lustrative and diagrammatic rather thanas'lim'iting me to my speclfic showing. In particular I .Wish-it to beunderstood that in illustrating the support pivoted to the carriage'Iemploy such a pivoted support as an'example of my preferred soluproblemand not as limiting me specifically to the use of a pivoted support.
